|discussion=<p>Rubus chamaemorus is circumboreal; it is presumed to be extirpated from New York, where it was known only from a single population on Long Island, far removed from the next southernmost localities in northern New Hampshire.</p><!--
--><p>Rubus chamaemorus is defined by its unarmed stems, simple, coriaceous, and plicate leaves, unisexual flowers, and golden yellow to reddish fruits. Rubus chamaemorus is likely an ancient allopolyploid (K. V. Ambrose 2006).</p><!--
--><p>The edible fruits of Rubus chamaemorus are highly valued in northern regions for consumption fresh and in yogurt, jams, syrups, and juices. An alcoholic beverage is made from the fruits and sold commercially in Newfoundland, Quebec, and Finland.</p>
